PAY-ROLL-GLCULATING MACHINE.

Application led September 1, 1915.

To all whom t may concern:

Be it known that I, THEoDoRE l). WIL- .LrAMs, of Rochester, in the county of Monclear, and exact description of the same,

reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon. l

My present invention relates to calculating machines and it has for its object to provide a simple andeiiicient machine having a relatively small keyboard for automatically computing and .registering payroll memoranda, that is, the number o pieces of money of each denomination that are required to provide the proper change for distributing the pay .in such manner t that the aggregate number of pieces of all v the denominations for which the machine 1s adapted is as small as possible. A further object of the invention is to provide a machine that will indicatethe number of pieces v,in eachJ tem of the payroll and also the total number for all items. Still another object is to combine'a machine of this character with the ordinary adding or calculating machine so that as the payroll items are added on the last mentioned machine, the proper denominational divisions thereof will automatically and by the same operation be computed on the first ymentioned machine. To these and other ends the invention resides in certain improvements and combinations of parts all as will be more fully described hereinafter, the novel features being pointed out in the, claims at the end of the Specification.

In the drawings:

ators together with the "mechanism by which they are connected up to a register;

Fig. 5 is a detail section taken substantially on the line 5-5 of Fig. 4;

Fig. 6 is a fragmentary view of a portion of the actuator mechanism of another group.

Similar reference numerals kthroughout the several figures indicate the same parts.

I will first describe the general construction and operation of my machine and eX- plain the net results accomplished by it and later explain its detail. In this View, 1 indicates generally Athe usual or any preferred form of adding machine having a keyboard comprising nine rows of keys A, B, C, D,

E, F, G, H and K with nine keys in eachy row numbered from one to nine, as shown. The row A is for the `units column of an amount expression, B the tens column, C the The operation of such a machine is thought to be too well known .to require description here beyond saying that the desired numbers in each column are selected by depressing the keys and the expression-is registered at 2 and printed at 3 on a web 4 that issues from the machine, the printing and registering of each following actuation of the lever 5' and totals being registered in the same way by also depressing the key 6 before the lever 5 is pulled. The printed total is shown at':

In the practice of myinvention, another calculating machine indicated generally 4at 8, of ve much the same general nature, is detachab y secured to the machine 1 by catches 9. It also has registers or accumulators a, b, c, d, e, f, g, h which, however, register numbers, separately read, that represent cents, nickels, dimes, ete. on the decif mal system up to twenty dollar pieces, as indicated thereon. These registrations are also printed in similarly designated columns across a web 10 both in separate items, as shown at 11, or in a total, as` shownat 12. Whenever an item is registered on the add-` ing machine, the same actuation of the. keys registers the fewest number of pieces of money that will go to make up that sum and ,indicates the denomination tof each. Thus, the rst item registered on the adding machine is $38.47 and the corresponding registration on the payroll web 10 shows one twenty dollar bill, one ten dollar bill, one five dollar bill, three one dollar bills, four dimes, one nickel and two cents. Running these down inthe order named, it will be seen that no greater number of the larger denominations could be used to reduce the number' of any smaller denomination required. The totals will similarly show that two twenties, two tens, three fives, eight ones, seven dimes," two nickels and seven pennies are required to makeup eighty three dollars and eighty-seven cents with the proper change for the items that constitute it.

The registers or recorders vof the payroll machine are, in the present instance, electrically actuated and automatically selected by contacts made with the keys of the adding machine. There are four actuators a, e2, a3 and a* for the cents register a; one actuator b for the nickels register I); four actuators c', c2, c3 and cL for the dimes rec;- ister c; one actuator CZ for the half dollars register el; four actuators c, e2, c3 and eL for the dollars register e; one actuator f for five dollars f; one actuator g for ten dollars g, and four. actuators it, h2, h3 and for the twenty dollars it. The actuators of each series are suitably arranged to respectively record 1, 2, 3 or 4 units on the corresponding re ister. More than four cents can be pai( with a nickel; amounts containing more than one nickel can be paid with dimes; amounts containing more than four dimes can be paid with half dollars, and so on. Hence, not more than four actuators are required in any instance and in several instances only one is required.

'The push rods or plungers that respectively turn the registers to a greater or-less degree are indicated at 13 in Figs. 3 and 4. In Fig. 4 is shown the row of actuators a, etc., with the mechanism throughwhich they turn the register a, it being understood that there is a corresponding mechanism for each row of actuators. The plungers project through a platform 40A and springs 41 bear against this platform and against collars 42 on the plungersto return the latter after being depressed. Pivoted at 43 on an ear 44 on the platform isa segment lever 45 geared with a rotary member 46 turning freely on the shaft 47 of register a. The member 46 carries a pawl 48 coperating with a ratchet wheel 49 on the first register wheel. As the lever 45 is rocked back and forth, the ratchet 48 turns the register wheel a given distance and then re-sets.. The lever 45 is rocked by a draw bar 50 pivoted to its lower end at 51l and guided in a .bracket 52 on the under side of platform 40. On shaft 53 of operating lever 5 is an arm`54 connected to the draw bar 50 by a spring 55. This spring normally holds a pin 56 on the draw bar against arm 54 and maintains the segment arm 45 and register a in the normal position of Fig. 4. When the lever 5 is pulled forwardiy, the arm 54 on its shaft 53 exerts a pull on the draw bar 50 through the medium of spring 55. But the draw bar is normally held against such movement by a latch 57 on a bell crank lever 58 pivoted to bracket 52 at 59. Pivoted to the bell crank 58 at 60 is a link 61 the other end of which link is pivoted at 62 to a second bell crank 63. The bell cranks are also connected by a bar 64 so that the link 61 has a parallel motion. The plunger-s 13 rest on the link 61 and when one of them is depressed, the link swings downwardly and disengages catch 57 from the draw bar 50. At the same time a stop 65 on the plunger is brought opposite a pin 66 on the draw bar. There is a pin and stop for each plunger, as shown, but in each instance, these two elements are separat-cd to a different extent. Thus, when the crank lever 5 is drawn forward, the draw bar 50 is shifted to the extent permitted by the stop 65 on the particular plunger 13 that has been actuated and has displaced the latch 57 and hence the segment lever 45 shifts the register e accordingly. If none of the plungcrs 13 of the row has been actuated, the bar 50, of course, remains locked and the pull of the arm 54 is taken up entirely by the spring The several wheels on the register a operate each other to accumulate amounts in the usual manner.

In 'the c'ase of a single actuator such as lb', cl etc., the draw bar 50 shown iirFig. 6 :'.s normally held locked, not by a latch 57 but by a shoulder 67 on the stop 65 with which shoulder the pin 66 is normally in contact. The plunger 13 'does not rest on the draw bar and when it is actuated, the shoulder 67 is displaced from the pin 66 and the latter is brought in contact with the face of the stop 65 in the manner previously eX- plained when the draw bar is shifted.

Each plunger is under the control of an arm 14 of a separate solenoid 15. The keys A, B etc... are fitted with insulated projections 16 'that operate switches or circuit closers 17, is, 19, 2o, 21, e2, 23, 24, 25, 2c, 27 2s and 29. Some of the keys are fitted with two switches for purposes that will hereinafter appear.

In Fig. 3 are shown in detail the row of units keys A capable of recording amounts "up to nine cents the row of actuators a,.etc.,

for the cents register a. and the actuator b for the nickels register b, and the circuit arrangements will be explained with reference to this group of keys. If it is desired to record one cent, the first key of the group A is depressed. This closes a circuit from battery 30 through main circuit 31, switch 17, wire 32, solenoid a, main wire 33 back to battery. The energized solenoid a draws down the arm 14 and depresses the plunger 13, actuating the register a through one count. Similarly, keys 2, 3 and 4 for respectively recording two cents, three cents and :tour cents are connected to energlze the solenoids ri', a2, a and ai. Whenv it coineskto the lifth key for recording five cents a circuit is closed from battery 30, main line 31, switch 21, wire 34, Wire 35, solenoid Z1', main line 334and back to battery. Thus, the actuating mechanism b of register b causes the registering of one nickel. ,I If the amount is more than five cents, say six cents, cireuitswill be established through both the solenoid a. and the solenoid 1)', as followsbattery 30, main line 31, switch 22, Wire 36, 'Nire"32, solenoid a, main line 33 and back to battery 30, on the one hand, and battery 30, main Wire 31, switch 23, Wire 37, Wire 35, solenoid b', main line 33 and back to battery. The result will obviously be that actuator a being energized and actuator b also, both register a and register b will be moved one count and one nickel and one cent 'will be -registered and printed on the payroll computer, making a total Nsix cents corresponding with the said srxth key of group A.

In the same Way, key 7 is connected to actuator b and actuator a2; key 8 to actuator b and actuator a3, and key 9 to actuator b and actuator a4. arran ements may be traced with respect to all (cys in groupsA, B, C and D, but it is not believed necessary to describe in detail the operation of the groups B, C and D 4as they are on exactly the same scheme as group A and it would needlessly complicate the showing to complete the circuit arrangements of the remaining groups. -Keys 1 to 4 of group B are connected, respectively, to actuators c', c2, 0"*` c4, for instance, while key 5 of the same group is connected to actuator d and the remaining keys 6, 7, 8 and 9 are respectively connected both to actuator d and actuators c', c2, c and 0*.

In order to make a unit of'the payroll computer 8, it is detachably secured to the adding machine 1 by the catches 9, as before described, and the electrical connections are established in the present instance through the provision of lugs 38 on one machine and sockets 39 on t e other, as shown in Figs. 1 and 2. y

It will be observed that my payroll computer utilizes the sim le keyboard of the adding machine and t at it does its Work in conjunction with the adding machine without interfering with the latter in any way and no mental processes whatever beyond those indulged in in operating an adding machine are required in connection with 0n Fig. 2, these circuit .v

the computer. lurthermore, it is obvious that the computer may be used separately from the adding machine, in Which phase of the invention the keyboard shown may be considered with respect to its circuit closing functions alone.
